Running dos command line from C#?

You can run a DOS command line from C# by using the Process class in the System.Diagnostics namespace. The Process class allows you to start an external process and interact with it programmatically.

Here's an example of how to run a DOS command line from C#:

using System.Diagnostics; class Program { static void Main(string[] args) { string command = "dir /s"; // DOS command to run ProcessStartInfo psi = new ProcessStartInfo("cmd.exe", "/c " + command); psi.RedirectStandardOutput = true; psi.UseShellExecute = false; psi.CreateNoWindow = true; Process process = new Process(); process.StartInfo = psi; process.Start(); string output = process.StandardOutput.ReadToEnd(); process.WaitForExit(); Console.WriteLine(output); } }

In this example, we define a DOS command to run by setting the command variable to "dir /s", which lists all files and subdirectories in the current directory.

We then create a new ProcessStartInfo object, which specifies the command to run and its arguments. We set the RedirectStandardOutput property to true so we can capture the output of the command, and the UseShellExecute and CreateNoWindow properties to false and true, respectively, to prevent the command prompt window from appearing.

We create a new Process object and set its StartInfo property to the ProcessStartInfo object we created earlier. We then start the process by calling the Start method.

We use the ReadToEnd method of the StandardOutput stream to read the output of the command, and then wait for the process to exit by calling the WaitForExit method.

Finally, we display the output of the command on the console using the Console.WriteLine method.

Note that you can replace "dir /s" with any other DOS command that you want to run. You can also capture the error output of the command by setting the RedirectStandardError property to true and reading from the StandardError stream.
